Code Metrics Analyzer

Measure code quality through various metrics.

Capabilities

Calculate cyclomatic complexity
Measure code coverage
Analyze lines of code (LOC)
Count methods/functions per file
Measure comment density
Identify complex methods
Track metrics over time
Generate quality reports
Find refactoring candidates

Tools

code_metrics.py

- Calculate various code metrics

Metrics Calculated

Cyclomatic Complexity - Decision point count
Cognitive Complexity - Mental effort to understand
LOC - Lines of code (total, code, comments, blank)
Method Count - Methods per class/file
Depth of Inheritance - Class hierarchy depth
Comment Ratio - Comments vs code
Test Coverage - Percentage tested

Commands

# Analyze project
./code_metrics.py analyze --source-dir PaleoRose

# Find complex methods
./code_metrics.py complex --threshold 10

# Generate report
./code_metrics.py report --format html
